If a crane's jib is offset by 15° while the boom angle stays unchanged, what happens to the load radius?

When a crane's jib is offset, the load radius is affected because the angle at which the jib extends changes the horizontal distance from the center of the crane to the load being lifted. When the jib is set at a 15° offset, this effectively extends the reach of the crane further away from its base. The load radius, which is the horizontal distance from the center of the crane's rotation to the load being lifted, increases as a result of this offset.

This means that despite the boom angle remaining unchanged, the load is positioned at a greater distance compared to the situation when the jib is not offset. The increase in the load radius can result in a change in the lifting dynamics, including the crane's capacity to safely lift a load at that extended reach. Understanding this relationship is crucial for safe crane operation, as it impacts both stability and load charts.
